Question

I summed my square-side seven times and the area eleven times so that it was 6;15. What is the length of the side of my square

Answer 1

1 ÷ 2

Explanation:

Given that

The square side is seven times

And, the area is eleven times

So it is 6;15

We need to find out the length of the side of the square

So,

let us assume the side of square be S

Now the area is S^2

Now

11S^2 + 7S = 6.15

11S^2 + 7S - 6.15=0

Now the quadratic equation should be followed

= (-b+- √ (b^2-4ac)) ÷ 2a

Here a = 11,b = 7,c = -6.15

so

S = 0.4944, -1.1307

As we know that the side cant be negative so

Therefore

S = 0.4944 ≈ 0.5 = 1 ÷ 2
